Can take a long while to heal. I had AT in one foot and it took 15 months before it cleared up to the extent that I have forgotten I had it. Now completely healed with no hint of re-occurrence - 2 1/2 years now. No lumps/bumps to see, either.
I got to this stage through careful management and excellent service from a sports injury therapist doing regular deep tissue massage.
You are not more prone to have it happen again (unless you repeat any mistakes that might have caused it in the first place).
I'd continue with heel drops and calf stretches as good preventive medicine, take care with shoe purchases to not choose models that aggravate the tendon (look for a low back).
For your first runs take it very steady - no speedwork or downhills. Find a flat, smooth surface and see how you get on. If the pain is very acute or sharp you should stop but if only dull throbbing persevere - you will find it will ease off after a few miles. If it comes back later on in the run that's about the time to stop.
Build up obviously very slowly indeed.
